I have a number of 2600 series routers that I need to upgrade the IOS on to support MLPPP and multiple T1 circuits. I have not upgraded the IOS on a router since taking Cisco classes and doing so in a lab setting years ago. I know performing the upgrade via a TFTP server is much faster than using the console port and XModem. Is there a certain TFTP server you recommend over others that I can download? If I install the TFTP server on my laptop and have the router in question setting here on my desk, do I connect to the fastether net port of one of the serial ports? Can I do so via a straight through cable, or is it best to route it through my network on the same subnet? Any other guidance you can provide would be appreciated. I will NOT be performing these upgrades remotely, but will have all the units here where I can get my hands on them.
